CAN-FAUCET.

SPECIFICATION forming part of Letters Patent No; 520,840, dated June 5,1894.

Application filed March 22, 1894.

T alt whom it may concern:

1 3e 1t known that I, GEORGE W. BANKER, a citizen of the United States,and a resident of Keene, in the county of Essex and State of New York,have invented certain new and useful Improvements in Can-Faucets, ofwhich the following is a specification.

My invention relates to improvements in i can faucets and it has specialreference to the method of fastening the taggers tin sealing piece tothe bottom of the faucet cup; and alsoto 1m proved means for holding thepackmg in the bottom of the cup; and also to certain details ofconstruction, which will be explained in the following specification.

PIlOI' to my invention, it has been customary to solder the thin taggerstin sealing piece to the bottom of the cup of the faucet, ordinarily onthe outside thereof, and also special means have been provided forholdmg the packing in the bottom of the cup; but sometimes the packinghas not been fastened, it then frequently resulted that the outwardmovement of the liquid from the can would displacethe packing,occasioning trouble for its re-ad ustment. Also in some kinds offancets, the packing is attached to the valve itself, lnstead of beingplaced in the bottom of the cup. Then this construction is employed, itis desirable to have a raised annular'rib formed in or upon the bottomof the cup, down upon which the packing of the valve may be pressed tosecure positive sealing of the opening. My invention provides for thisconstruction of faucet also.

In the drawings hereof: Figure 1, represents a section of a low downfaucet, embodying my invention. The joint between the taggers tin andcup of the faucet is shown as not yet swaged to place. Fig. 2,represents a sectional View of the cup shown in Fig. 1,t-he taggers tinand packing being in place, and the parts swaged down. Fig. 3, shows asectional view of the cup of a faucet, showinga sllghtly modified formof joint between the taggers tin and the cup. Fig. 4, shows a sectionaland perspective view of a cup with its taggers tin sealing piece, therebeing no packing. This cup being intended for use in a faucet, in whichthe packing is attached-to the Valve.

A is the cup of the faucet. B is the flange Serial No. 504582. (Nomodel.)

at its upper-edge, which is attached to the body of the can. 0 is thebottom of the cup. D is the packing material. E is the removable top ofthe faucet, having threads F,-

which engage with the threads on the cup A. G represents the exterior ofa recess or chamber made in the cover E, within which a threaded nut isconfined, which engages with a threaded spindle II, which is providedwith a thumb nut I on its upper end. J is the valve attached to thelower end of the spindle H. I show it as having corrugations K, K, &c.,whereby it is stiffened. L is the spout, which is attached to the upperpart of the cover. All these parts are or may be of any preferred.construction, and the faucet may be other than the so-called low downkind.

, The parts more particularly involved in my invention are as follows:

. M is the taggers tin sealing piece.

N is an upwardly turned flange, which extends entirely around the edgeof the taggers tin.

O is a concave flange or rib for-med all about the opening in the bottomof the cup at the edge thereof, and the flange on the taggers tin andthis concave rib on the bottom of the cup are made of such relative sizeand shape that the flange on the taggers tin may be easily introducedwithin the rib on the cup bottom, in such manner that when the parts areswaged down by properly constructed squeezing dies, the two parts willbe firmly pressed and bound-together, so as to make a water-tight joint,and also I so construct the squeezing dies that when thejoint is madebetween the taggers tin' and the joint bottom as above stated, the metalwill be rolled outwardly and impinge upon or slightly overlap the inneredges of the ring like packing. This is shown in Fig. 2. I cannotillustrate the metallic parts as closely together as they are in fact,because there is then no dividing line to be seen between them. I leavethe joint a little open so that the construction may be more easilyseen.

It will be observed that under my construction I entirely do away withthe expensive process of soldering the taggers tin to the cups, and alsothat by one and the same operation, which is much simpler and lessexpensive than the solderin g process, I not only secure a tight joint,but also clamp the packing in position so that it cannot becomedisplaced. In addition to which, the faucets are smoother and handsomerboth inside and out, than any other construction known to me.

I do not restrict myself to any special kind of packing, nor, as stated,to any special construction, nor to the form of interlocking edges shownin Figs. 1 and 2. Any desired shape or form may be given to theseinterlocking surfaces, as is well-known in the tinners or pressed-metalart. For some liquids the joints should be more thoroughly and carefullymade than for others. The form shown by me in Fig. 1 will answer wellfor certain liquids and in Fig. 3, I illustrate a form which will make amore secure joint, useful for more penetrating liquids. In it, theinterlocking edges have greater area of interlocking surfaces. Asstated, however, any other preferred form or shape may be given to theseinterlocking edges, as is well-known in this art.

In certain kinds of faucet, the packing is attached to the movablevalve, and then it is desirable to have a raised rib or upwardlyprojecting part on the bottom of the cup of the faucet, which shallengage forcibly with the packing on the valve, when it. is seated, so asto make a positive seating joint all around the valve opening. This isfrequently desirable if not essential to avoid metal contacts, owing tothe construction of the parts.

In Fig. 4, I show this construction; it is substantially that shown inFig. 3, with the packing left off.

I claim- 1. A can faucet having a taggers tin sealing piece attached tothe cup by interlocking 4o edges and a packing in the bottom of the cup,upon which said interlocking edges impinge, substantially as set forth.

2. A can faucet having a taggers tin sealing piece attached to thecentral part of its 5 bottom by interlocking the edges of theopening inthe cup with those of the sealing piece, and a ledge on the bottom ofthe cup outside of the said interlocking edges, adapted to receive thepacking for the valve, substantially as set forth.

3. A can faucet having a taggers tin sealing piece attached to thebottom of the cup of the faucet by interlocking edges, which interlockededges project upwardly above the plane of the bottom of the cup,substantially as set forth.
